Donald Trump, exposed Wednesday as an alleged serial groper, once said he’d spotted his future girlfriend on an escalator — when she was only 10.

The would-be sexist-in-chief made the stomach-turning joke in 1992 when “Entertainment Tonight” taped a Christmas special in Trump Tower.Trump, then 46, makes a brief appearance and asks a group of 10-year-old girls if they’re going to take the escalator, according to the footage, reported by CBS News Wednesday. One girl pipes up with a happy “Yes!”

“I’m going to be dating her in 10 years,” Trump leers. “Can you believe it?”

The sickening segue wasn’t even the worst news to break about Trump on Wednesday. Five women came forward to say Trump had groped them against their will — just days after the Republican candidate said his vulgar 2005 boastthat he could grab women “by the p—y” was just “locker room talk.”

Thirty years ago, Jessica Leeds of Manhattan encountered Trump on a flight, she told The New York Times.

She said he began to fondle her, grabbed her breasts and tried to snake his hand up her skirt. “He was like an octopus,” Leeds, 74, told the Times. “His hands were everywhere. It was an assault.”

Former receptionist Rachel Crooks, meanwhile, said she ran into the misogynist mogul in Trump Tower in 2005. She claims Trump grabbed her and began slobbering on her cheek, and then kissed her on the mouth.

“I was so upset that he thought I was so insignificant that he could do that,” Crooks told the Times.

Trump issued a blanket denial in Sunday night’s debate when asked if he’d ever acted on his bullying “grab ’em by the p—y” brag.

“It’s just words, it’s just words,” he insisted. The bombastic businessman also denied the allegations put forth by Leeds and Crooks.

“None of this ever took place,” Trump, 70, shouted at the Times reporter.

“For The New York Times to launch a completely false, coordinated character assassination against Mr. Trump on a topic like this is dangerous,” he said in a statement.

“To reach back decades in an attempt to smear Mr. Trump trivializes sexual assault, and it sets a new low for where the media is willing to go in its efforts to determine this election.”

A Trump spokeswoman contacted by the Daily News said there were no additional comments.

Trump was drafting a defamation lawsuit against the Times Wednesday night, ABC News reported.

The Times reporter who interviewed Trump, Megan Twohey, received a legal letter from a Trump attorney Wednesday afternoon, she told CNN. A few hours later, the Times published its story.

A third woman also came forward to the Palm Beach Post on Wednesday to say she’d been groped by Trump in 2003 at his Florida resort.

“Donald just grabbed my ass,” she told a companion right after he groped her, the newspaper said.

Sources in Trump’s camp told CNN he was drafting a lawsuit against the Palm Beach Post as well.

Cassancra Searles, Miss Washington 2013, also spoke up Wednesday, claiming Trump repeatedly grabbed her buttocks and begged her to come to his hotel room when he owned the Miss Universe pageant, NBC reported.

Later Wednesday, People magazine writer Natasha Stoynoff posted a piece claiming Trump cornered her at Mar-a-Lago in 2005, and shoved his tongue down her throat with his pregnant wife Melania upstairs.

“Have you ever been to Peter Luger’s for steaks? I’ll take you. We’re going to have an affair, I’m telling you,” she said he told her.
